I feel like the further this game goes on, the fewer the fetishes that appeal to me.
I speedran it at some point through rampant abuse of the noclip cheat and exploiting of the save / heal points and how they reset the character. The fetishes are interesting in their arrangement.
At the start it opens with typical slime and spider girl, normie stuff. Then it starts going into worm parasitism, think of it like tentacles. Shota appears once to then appear much later in a very weird way. Next is giant flies, which is oddly common in Japanese porn and likely to turn off westerners. Then after the traumatizing parasite-insect-vore-tentacle turducken boss fight (you'll know it on sight), hypnotic bodysuit monster appears. Then parasitized zombies, then robot machines, vats, and mechs in parasite bug form.
I gotta throw my preferences to the side and admit that this is technically a good game. I think the engine choice is insane and dated, and it took me a while to accept "porn" to merely mean "this looks phallus-shaped, good enough" as a concession for learning to like the creativity of the hentai. However despite being in Macromedia Flash, the developer gives decent platforming in significant amounts, has a stat and equipment system, and most importantly for people who want hentai, it is freely accessible to an unusual degree; not only is there the typical gallery on the main menu, but every time a monster grabs you it opens up a dynamic scene player to deeply control the playback of a long multi-part scene, and also take control of some monsters and play as them with your controls.
I think the game is good - it has significant freedom given to the player, yet if you dared play fairly the game is difficult to a high degree even on normal mode. The 5 difficulty options seem to determine the invulnerability period before an active hitbox can hit again, which means on higher difficulties just touching anything that deals damage can multi-hit combo your health away in a huge chunk. To play as intended, imagine it's a platform fighter and try to launch foes. If they're weak, hold back and launch them away, then repeat. If it's a boss you can juggle, please do juggle it and be prepared for when it aggros and breaks out your juggling. If the boss is immobile, it's pure bullet-hell mechanics, you'll spend more time shooting than doing melee.
This game is bewildering the whole way through. I did not like it the first time I picked it up, not even my 2nd time. On the 3rd time I realized it's pretty good for a hentai game.
